Invasive lobster-like crawfish that can grow up to 2 pounds discovered in Texas
TPWD Aquatic Biologist Dr. Archis Grubh said he found three additional redclaw in July, two miles away from the apartment pond.
"We don't know when these invasive crawfish were first introduced or how far they have spread, but we do know they can have a negative effect on local species and biodiversity," Grubh said in a release.Regardless of their taste, the species is extremely invasive and any sighting should be reported to TPWD.
A single redclaw can can grow up to two pounds in under a year and produce offspring five times a year at 1,000 eggs per clutch, according to TPWD. The crawfish eat decaying plant and animal matter, which, due to their large size, can alter habitats and clear out local vegetation. Because they breed so many at once, they can make life harder on small fish by consuming the local food., eradication is almost impossible.
"Spreading the word about this invasive species and reporting sightings to TPWD can help us better understand where it is distributed and potentially take steps to help prevent its spread," Grubh said.
